Foxboro 871CC Sensors (Cells), in conjunction with supporting 871CC accessories, offer a dependable, fast, durable, and in-line means of measuring ionic content of a sample stream. As symbolized by the “CE” Logo marking on the product, these sensors conform to the applicable European Union directives when used with the electrochemical analyzers listed below.

INTRODUCTION

871CC Contacting Conductivity/Resistivity Sensors are used with Foxboro 873CC, 873RS, 873ACC, 873ARS, 875CR, and 870ITCR Electrochemical Analyzers and Transmitters to detect the conductivity or resistivity of a solution. The analyzer applies a low frequency voltage or current across the sensor electrodes in contact with the process fluid. The resulting electrical parameter is sampled, interpreted, temperature-corrected, and displayed by the analyzer.

APPLICATION FLEXIBILITY

A choice of two cell factors, 0.1 cm-1 and 10 cm-1, is available for conductivity measurement. The required cell factor is dictated by the measurement type and range. Resistivity measurements always use a sensor having a cell factor of 0.1 cm-1. Conductivity measurements utilize both cell factors. 871CC Sensors are offered with a wide variety of mounting options and a choice of two temperature elements.

PSS 6-3C2 APage 2

QUALITY AND UNIFORMITY

871CC Sensors are manufactured under strict guidelines of quality and uniformity to ensure that all cell factors are within 2% of their nominal value. All sensors with 0.1 cm-1 cell factor (CF) have the actual CF stamped on the sensor. The actual CF is determined using NIST traceable quality procedures. Optionally, resistivity cell factors can be determined in a Foxboro ultra-pure water loop (Options Code -9).

Simply enter the CF and temperature CF into the applicable factory-calibrated analyzer and you have a fully-calibrated measurement system!

INTEGRAL TEMPERATURE SENSOR

All sensors use an integral temperature element whose signal is used by the analyzer for temperature compensation and measurement. Sensors are available with either a 100 kΩ thermistor or 100 Ω RTD. For elevated temperatures, the 100 Ω RTD is recommended. Optimum positioning of these transducers within the sensor ensures close thermal contact with the process and, thus, rapid response to temperature change.

Temperature cell factors (tCF) are determined and stamped on each 0.1 cm-1 cell-factor sensor. This factor indicates the offset, in ° C, resulting from the resistance of the RTD or thermistor cable. Entering this value into the analyzer or transmitter accurately calibrates the RTD or thermistor to the instrument.

TITANIUM, MONEL AND CARBON ELECTRODES

The 0.1 cm-1 CF sensor is constructed with titanium or Monel™ electrodes. Titanium oxidizes naturally to form a chemically passive but electrically conducting surface. It is compatible with most fluids except acidic fluorides. For applications using acidic fluorides, Monel electrodes can be used. The electrodes have a concentric cylinder configuration.

The 10 cm-1 cell-factor sensor uses high density graphite electrodes.

VARIETY OF ACCESSORIES

A large selection of accessories is offered to meet virtually all process requirements. This includes process-mounting accessories such as flow chambers, gate valve assemblies, and tees.

ACCESSORIES (Cont.)

Gate Valve Assembly

A gate valve assembly enables the user to easily install and withdraw the insertion sensor (Sensor Body Code -D or -M) while the process is pressurized. The small diameter insertion shaft gives a 1:10 ratio of insertion force to process pressure e.g., at a process pressure of 1.4 MPa (200 psi), only 89 N (20 lbf) is required to insert the sensor. The damping effect of process liquid, trapped behind sensor, adds a safety factor by slowing the passage of the sensor into the isolation chamber. See Tables 3 and 4 for additional specifications and Part Numbers. (a) For use with 871CC-D or 871CC-M Sensor. Sensor is not

included with the Valve Assembly.

(a) The o-ring is located on the Sensor Assembly and is not part of the Gate Valve Assembly.

Flow Chambers

Flow chambers offer a convenient way of mounting sensors in a system where the sample is provided by a small diameter sample line. The flow chamber connects to the system via user supplied 1/4 NPT

fittings and provides a chamber for the sample. A flow chamber with a sensor in place will pass up to 125 mL/s (2 gpm) of sample. See Table 5 for additional specifications and Part Numbers.

Junction Box (Not recommended for resistivity measurement)

The junction box (Figure 1) mounts to a surface and provides a convenient means of connecting the sensor cable to the extension cable (see Extension Cable Assembly section). The junction box is weatherproof and dusttight as defined by IEC IP65 and provides the watertight protection of NEMA Type 4. Specify Part Number 0051052.

Extension Cable Assembly (Not recommended for resistivity measurement)

The extension cable assembly (Figure 2) is a PVC-jacketed multi-conductor cable with numbered leads, and is terminated with spade lugs on both ends allowing it to be connected to the terminals in a junction box (Figure 1) and in the measuring instrument. See Table 8 below for cable application, Part Number, and maximum allowable total cable/patch-cord length between the sensor and the instrument.

Extension Cable (Not recommended for resistivity measurement)

The extension cable (Figure 3) is a PVC-jacketed multi-conductor cable. The cable is not dressed and has no terminations. See Table 8 below for cable application, Part Number, and maximum allowable total cable/patch-cord length between the sensor and the measuring instrument.

Patch Cord (Not recommended for resistivity measurement)

Patch cords (not shown) provide connections between sensors with optional suffixes -5, -6, -7, and a transmitter, analyzer, switch, or junction box. One end of the patch cord has a socket for connection to the sensor; the other end has numbered leads. See Table 8 below for patch cord application, Part Number, and maximum allowable total cable/ patch-cord length between the sensor and the measuring instrument.
